Purpose of the development: Device allows to assess the state of working equipment and prevents the occurrence of accidents in the factories of oil refining and chemical industries.

Recommended application field: For corrosion monitoring equipment oil refining and chemical industries, and assess critical state.

Technical characteristic: The device is a dual-channel with a resistance of 10 megohms. Spans input 1 0 1 Channel B, 2nd -1.2 + 1.2 V. The number of registration points on each channel - 192 512. The boundaries of the tolerable basic error of measurement of instantaneous current parameter values in digital form as a percentage of the display range - ± 0,25%. Equipped PS485 interface to communicate with the computer at a rate of 38400 bps. The possibility of the introduction of digital filters for noise reduction. It is possible to select an input value is considered a pulse of 1 to 20 mV / s. instantaneous registration period parameter from 0.1 to 60 seconds. The magnitude of interference and its level range is set manually (2 to 20 mV). Provided the revision of the schedule of change of the parameter throughout the depth of the archive with the withdrawal date and time and the instantaneous value of the parameter in digital form at each point. file storing time recording frequency of 1 min up to 100 hours. There are warning of achieving measurable allowable parameter values. The device ensures the safety of data when power is turned off with the possibility of time control off state. Intrinsically safe execution.

Advantages over analogues: The results obtained do not have analogues in Ukraine. The device implements a pulse method for determining the critical state of the existing equipment.

The development stage readiness: Introduced in production

Description of the development:
()
Device is constructed on an analog-digital converter and a microprocessor, random access memory and nonvolatile memory converter that provides charge information in two channels: - the first - recorded analog electrochemical parameter change in the accumulation of damage in the metal; - the second - the amount of electrochemical pulses, indicating the development of cracks in it. The device is mounted in a measuring circuit with single-electrode sensor. Measure the potential difference between the sensor and the controlled portion of the metal equipment. The main criterion by which to assess the extent of damage to metal is intermittent (pulse) the nature of the changes of the electrochemical response to the growth of cracks. The device allows you to start the monitoring process of the chemical industry equipment at any stage of its operation and ensures the establishment of the degree of damage, do not require prior experimental determination of electrochemical characteristics of deformed metal.
